This study investigated supervisees' perceptions of the learning processes and outcomes of professional supervision. Two hundred and sixty-four psychology graduates involved in the process of professional supervision for registration responded to a mail survey regarding their supervisor's approach to supervision, their own approach to supervision and their perceptions of the overall effectiveness of the process. Findings suggest that professional supervision can be readily conceptualised as a learning relationship. Supervisees' approaches to supervision comprised the three dimensions of surface-disorganised, evaluation anxiety, and endorsement of supervisor capability. Supervisors' approaches to supervision were understood by supervisees in terms of facilitative and didactic approaches to learning. A facilitative approach to supervision was associated with enhanced evaluations of supervisor capability and a reduction in supervisee confusion and anxiety. A facilitative, but not a didactic, supervisory approach positively influenced supervisees' perceptions of the effectiveness of supervision. (Contains 4 tables.)
